How This Calculator Works

Calculation methodology and assumptions

This calculator estimates Illinois's Temporary Total Disability (TTD) workers' compensation benefit -- the ongoing wage-replacement payment made while you are completely unable to work due to a job injury -- using 66 2/3% (two-thirds) of your average weekly wage, per 820 ILCS 305/8(b). Illinois follows the standard nationwide formula: two-thirds (66 2/3%) of your average weekly wage. Your actual benefit is also subject to 133 1/3% of Illinois's state average weekly wage in covered industries, republished by the Illinois Workers' Compensation Commission every January 15 and July 15, on the high end, and 66 2/3% of the higher of the federal or Illinois minimum wage times 40 hours (with a 10-percentage-point-per-dependent increase to this specific minimum-wage floor calculation, capped at 100%) -- not a fixed dollar figure, so not hardcoded here, on the low end -- both change periodically, so this calculator shows the uncapped percentage-of-wage amount, and you should confirm the current published cap/floor with Illinois's workers' compensation agency before relying on this estimate for a specific dollar figure.

Frequently Asked Questions

How is a workers' comp TTD benefit calculated in Illinois?

Illinois pays 66 2/3% (two-thirds) of your average weekly wage while you are temporarily and totally unable to work due to a job-related injury or illness, per 820 ILCS 305/8(b).

Is there a maximum or minimum weekly benefit?

Yes. The benefit is capped at 133 1/3% of Illinois's state average weekly wage in covered industries, republished by the Illinois Workers' Compensation Commission every January 15 and July 15, and floored at 66 2/3% of the higher of the federal or Illinois minimum wage times 40 hours (with a 10-percentage-point-per-dependent increase to this specific minimum-wage floor calculation, capped at 100%) -- not a fixed dollar figure, so not hardcoded here. Because these figures are typically tied to a state average weekly wage that is republished annually, check with Illinois's workers' compensation agency for the current dollar amount rather than relying solely on this calculator's uncapped estimate.

Does this calculator estimate my lump-sum settlement amount?

No. This tool estimates only your ongoing weekly wage-replacement (TTD) benefit while you remain temporarily and totally disabled. A lump-sum workers' comp settlement additionally depends on your permanent impairment rating, future medical costs, vocational/return-to-work factors, and case-specific negotiation between you (or your attorney) and the insurer -- none of which a wage-replacement calculator can responsibly estimate.

What counts as my "average weekly wage" in Illinois?

Most states calculate this from your gross wages (before taxes) over a set look-back period before your injury -- commonly 13 weeks, though some states use up to a full year for seasonal or part-year workers. Check with your state's workers' comp agency for the exact look-back period that applies to your claim.

Are workers' comp benefits taxable?

No. Workers' compensation benefits paid under a workers' comp act are generally fully exempt from federal and state income tax, per IRC §104(a)(1) -- unlike a lawsuit settlement for lost wages, which is typically taxable. See our Legal Settlement Tax Calculator if you're dealing with a separate personal injury lawsuit rather than a standard workers' comp claim.
